To whomever it was that suggested I work through the wheel wells on my truck to get the spark plugs, it worked, thank you. I suppose I should really upload some pictures to show you guys what I've been working on. No pics of the tune-up today, but at least I have the pictures I took before I started painting it. Pics should be up tonight later or tomorrow or next week, if you're REALLY that interested, check back

yea wheelwell access is becoming mandatory it seems on new trucks. Chevy likes to shove their duramax fuel filters down behind the passenger wheel so you have to remove the splash guard to get to it. Good to hear you got it all fixed
